It's pretty simple. Rattle trap exhaust is now smooth reving, with zero loss of power after updated dyno. Only issue would be weight, pretty heavy part to add in. One of the ideas behind this Hummer H3 was to reduce weight and all lite weight exhaust just got killed back to stock weight with this installed.

I only have an inline 5 cylinder egine so I wanted good performance,sound and better fuel economy. Thats what I got with the super 10. It added a better sound and tone to the inline 5.

My ears are bleeding.... I love it. For real though, it's a little louder in the cab than I wanted, but I'm glad I didn't go with the Super 10. Good price, gotta love AutoAnything. Had it welded, only way you should do it really, and appearance I could care less about because no one is going to be looker underneath my truck.
